MEM and bill are the same. Schneider make square D kq and Merlin gerin. Although the same mcb Square d are plug on and Merlin are not. You used to be able to remove the plug on part of the square d mcb so you could fit it in a merlin board but they glue them in now . I think a lot of the no makes use the same casing.
I don't know all the brand nuances so more of this please 👍

Any help the community can be PLEASE DO, some brands may be wholesaler specific; Denmans doing Steeple i think is such an example - handy when the old brand goes but the wholesaler does not. All the nuance crap too like Electrium being behind several brands etc, all this stuff is useful and likely stuff the more....seasoned....sparks will know. Give me everything you got!

Regarding Steeple, this web page from Denmans lists a Lewden RCD, stating: "RCCB 80A 30mA compatible with Denmans Steeple and Curve consumer units."

Edit: link: Lewden 80/30/2A | Lewden 80A 30mA 6KA Type A RCCB (80/30/2A) | Denmans - https://www.denmans.co.uk/den/root-category/Power-Distribution-%26-Circuit-Protection/Consumer-Units-%26-Devices/Domestic-RCDs/Lewden-80A-30mA-6KA-Type-A-RCCB-%2880-30-2A%29/p/2501148587

However...:

(Maybe the Lewden one is compatible with a different Steeple RCD... but clearly not this one!)
